2.INSTALLATION

2.1 Pre-Installation Instructions

Make sure that the input power of the inverter is off.

2.2 Installation Procedure

(1) Securely insert the connector of the option unit far into the connector of the inverter. At this time, fit the

option fixing holes snugly. For the position of slot, refer to the next page.

Also be sure to fit the unit into the option fixing hook (For the FR-A500(L)/ FR-F500(L) series, it is avail-

able in Aug., 2000).

(2) Securely fix the option unit to the inverter on both sides with the accessory mounting screws. If the

screw holes do not match, the connector may not have been plugged snugly. Check for loose plugging.

With input power on, do not install or remove the option unit. Otherwise, the inverter and

option unit may be damaged.

INSTALLATION

CAUTION

1. Only one type of option per inverter may be used. When two or more options are mounted, pri-

ority is in order of slots 1, 2 and 3, the options having lower priority are inoperative.

2. When the inverter cannot recognize that the option is

mounted, it displays the option error. The errors shown

differ according to the mounting slots 1, 2, 3.

INSTALLATION

2.3 Wiring

Route the wires so that they do not take up a lot of space in the control circuit terminal block of the option unit.

During wiring, do not leave wire off-cuts in the inverter. They may cause a fault, failure or malfunction.

Use the space on the left side of the control circuit terminal unit to route the wires.

REMARKS

The wires with large gaze may not be connected to the terminal block. When connected in parallel, all wires may not

fit in the wiring space due to the increased number of wires. In such cases, perform wiring by using a junction termi-

nal block.

Do not use empty terminals as junction terminals because they are used in the option unit. If

they are used as the junction terminals, the option unit may be damaged.

When installing the inverter front cover, the cables to the inverter's control circuit terminals

and option terminals should be routed properly in the wiring space to prevent them from

being caught between the inverter and its cover.

3.FUNCTIONS

3.1 Internal Block Diagram

3.2 Terminals

* The operation of each relay depends on the output signal selected.

You can select any three output signals available with an

inverter as standard, and output them as relay contant signals.

Functions arailable differ between FR-A500(L)/F500(L) series

and FR-V500 series.

The output signals to be selected differ according to the inverter.

Refer to the instruction manual of the inverter. (output terminal

4.PARAMETERS

4.1 Parameter List

By installing this option unit, the parameters below are extended.

Set the values according to need.

The setting value of the parameter differs according to the inverter. Please refer to the inverter instruction

manual (output terminal function selection (Pr. 190 to)). (The setting value of negative logic can not be set.)

Parameter Number Name Setting Range Factory Setting

320 RA1 output selection 0 to 99, 9999 0

321 RA2 output selection 0 to 99, 9999 1

322 RA3 output selection 0 to 99, 9999 2

5.THE COMMERCIAL POWER SUPPLY-INVERTER SWITCH-OVER SEQUENCE FUNCTION

If the commercial power supply-inverter switch-over sequence function is activated with the FR-A5AR mounted on

the inverter, the phenomenon where magnet contactor switches alternate between ON and OFF may occur.

To prevent this, adapt either connection shown below.

(1) Recommended connection example 1

Use inverter output terminals (Contact sig-

nal, open collector signal) instead of MG1

signals.

The phenomenon occurs when relay out-

put of the FR-A5AR is used as MC1 signal.

(2) Recommended connection example 2

When using relay output of the FR-A5AR,

set the alarm output signal (ABC) instead

of the MC1 signal and output it from con-

tacts B and C.

CAUTION

For the FR-V500 series, the commercial power supply-inverter switch-over sequence function can not be used.
